EXPAND-IT™ Brush Cutter Attachment
EXPAND-IT Brush Cutter Attachment is rated 4.8 out of 5 by 981.
Rated 4 out of 5 by from Multi tool capable I bought the brush cutter attachment to go along with my trimmer and the 40V battery is more than enough to handle most brush that I needed cut down. Very pleased.

Rated 5 out of 5 by from Works great! Where has this been all my life? I love it. I bought this to handle road-side brush on a Tennessee mountain. It works great. It goes through 99% of the crud growing on the sides of the road. This will save me HOURS for the quarterly road maintenance. I am using it with the 40v head (RY40250). Great combination.

Rated 5 out of 5 by from Great purchase, but with one minor flaw I purchased this attachment along with the RY40250 Ryobi 40V String Trimmer. I used it today for the first time along our driveway and was quite impressed at how well it cut down the saplings growing along the edges of the drive. My only complaint is with the wingnut the holds the J-handle together. It really should be metal and not plastic nylon, which strips too easily. Other than that, great product.

Rated 4 out of 5 by from Great on the tough stuff Handles the tougher weeds that clogged the string trimmer. I expected the blades to be sharp but this does the job.

Rated 5 out of 5 by from Exactly what I was looking for. We bought this Brush Cutter to cut through the tough weeds and small saplings that the string trimmer couldn't handle. There is no hesitation to how fast this cutter works through thick tough weeds and small trees. Great product!

Rated 5 out of 5 by from Quick work! I needed to clear along a fence row around the property and being very pleased with previously purchased Ryobi Expand-it tools, I thought I'd give this one a try. I was not disappointed. I completed a long stretch of clearing before the battery finally gave out. I highly recommend this tool attachment to anyone having the power head handle.

Rated 5 out of 5 by from Great product The brush cutter attachment was easy to attach and use. It cut through tall thick weeds and vines. It cleaned under and around shrubs. Wish I had purchased it earlier.

Rated 5 out of 5 by from Tough little tool. Included strap is helpful. Works great with thicker brush. Easy exchange between attachments. Shoulder strap makes carrying tool for longer periods much easier—and can be used with other attachments.

Rated 5 out of 5 by from The great eliminator. Easy to change devices. The blade works better than I expected. Batter life is enough to do my yard and recharge is quick.

Rated 5 out of 5 by from Easy as cutting through butter I don't particularly like the battery operated lawn equipment but this thing is a beast. It cut through rough brush with ease. I only wish it was sharper...
